`Application. tiled February 4, 1927. Serial lo. 185,793;

The subject-matterof this invention is a sewing machine comprising animproved device for repairing knitted goods, e. g hose, and the like. 1In knitting devices used heretofore for this purpose so-called tongueneedles penetrate the work and draw the l'workingthread from the otherside of the work through the latter forming the loops or stitches.

In contradistinctionl thereto, in the machine according to the presentinvention the working thread isibrought, similarly as in a sewingmachine, by an eyeletted needle through the work into the reach of agripper and a stitch needle. y

By means of this mode of operation which is ythe opposite of the formermethod the following limportant advantages are -obtained 1. The'perforating needle can be so selecbed for each piece o work to beperformed that it can pass to and fro through practicall every kind offabric or knitted material, owever fine the mesh or stitches, Withoutany danger o f tearing loop or stitches at the edge of the hole to beknitted.

2. As the workin thread never leaves the hole of the fee needle whichhas no movable tongue or latch, no knots and consequently no disturbancein working ycan occur during the 'feed of the thread, as is the case inmachines having tongue or latch needles.v

3. The last row of stitches can be nished on the machine, which in knownmachines must be done by hand after removal of the work.

4. The breadth of the patch can be varied according to the shape of thehole in the work for saving thread, whilst in known machines the breadthmust be made and maintained from first to last corresponding to themaximum breadth of the hole. v

5. The edges of the damaged part of the work are not strained by tongueor latch needles penetrating the fabric.

In the machine according to the present invention the sewing needle,when knittin serves as knitting needle and as thread fee er which isintended to bring the working thread for forming loo s and stitchesthrough the stretched wor and for bringing through within reach of thesewing ma-f chine gripper la loop that is held on the 'to the loop otherside of the workby a loop holder in` the path of the knitting needle andtransversely thereof. Between a framecarrying the work and the loopholder isfsituated a row of sinker or loop' needles moved indivlduallyto and fro 'in succession, which needles take up in order to the loo orstiches formed b the gripper and de iver them older before the formationof a new loop or stitch. v

According to another feature of the inventlon, the gripper is formed asa doubleended swingingngrip er'which can form stitches or loops in bothdirections ofswinging as it hastwo oppositely directed grippirllgpoints. urther, yaccordin to the invention there 1s provided a devicewhich theentire row of loop needles can he so shifted step-bysteptransversely to the loop needles that these needles are broughtinsuccession Within reach of a positively controlled slide that servesfor withdrawlng the loop needle situated in the path of the knittingneedle for the delivery of the stitch or loop held by it and forclearing the path of the knitting needle, and also serves for feeding itforward, for receiving the new stitch or loop, in the same row of theother loop needles.

Other features of the invention will bel` described hereinafter andpointed out in the claims. 1

an enlarged scale,

Figures 26, 27 and 28 are cross-sections thereof, and

Figure 29 is a plan of the loop opener.

According to the drawings, the base-plate 1 of the sewing machine isprovided at its rear end in the usual manner with a hollow upper arm 2which contains, likewise in known manner, a driving shaft 3 and drivingmechanism for a needle rod I4 and a thread feeder 5. These parts areonly part-ly shown and may be formed 1n any convenient manner.

At the underside of the base-plate 1 is arranged a trough-shaped casing6 having in its bottom a broad groove 7 wherein a slide 8 is slidablelengthwise of themac'hine. This slide can be fixed in its end positionsby any convenient means, not illustrated. For using the machine forsewing the slide is fixed in its rear position shown by broken line inFigure 1; in the front position shown in full lines in Figure 1, theslide is placed ready for using the machine for knitting. In orderconveniently to shift the slide 8 from one end position into the other apivot 9 depends from the slide through a longitudinal slot 10 in thebottom of the casing 6 and through a lever 11 which is rotatable about apivot 12 and can be grasped by a hand at its free end.

A gripper shaft 15 is journaled in an upwardly extending arm 13 fixed onthe bottom of the casing 6 and in a cross-bar 14 fixed at both ends inthe latter. This shaft carries at its rear end a pinion 16 that mesheswith a considerably larger toothed wheel 17 carried by a horizontal axle18 rotatable on the pedestal of the upper arm 2. On the rear face of thegear wheel 17 is arranged a link 19, into which extends a pin 20 of aconnecting rod 21 pivoted in the usual manner to a crank, not shown, ofthe driving shaft 3. The pivot pin extends also into a slide block 22 ofa link 23 which is mounted to rock at about the middle of its lengthabout a pivot 25 rotatable in the rear wall 24 of the casing 6. Thislink 23 is locked in one 4of the. slanting positions shown in Figures 10and 11 by one or other of two pawls 26 and 261, whichever engages in thelower end of the link 23. During the upward and downward movement of theconnecting rod 21 the pivot 20 slides, according to the position of thelink 23, on

one or other side of the vertical plane pass" ing through t'he pivots 18and 25, as the pivot 25 is situated below the pivot 18 and the block 22moves only in the upper half of the link 23. According to the positionwhich this link occupies, therefore, the pin 20 drives the wheel 17 onone side or the other. The gear ratio of the two wheels 16 and 17 is soselected that when the wheel 17 rotates 90- the wheel 16 rotates about250.

The front end of the shaft 15 carries a double gripper having twogripper points 271 spaced apart and directed towards one another,between which the sewing or knitting needle 28 of the needle rod 4extends when the gripper is in the position shown in Figures 4 and 16.The two 4gripper points enable the gripper to form loops or stitcheswhen swinging in either direction out of the start-ing position shown inF igures 4 and 16. The gripper 27 serves, when sewing, like an ordinaryring gripper for receiving the lower thread-spool 29 and for formingloops, but works, when sewing, in only one direction, whilst whenknitting it works in both directions alternately for .forming rows ofloops. When not in use,

i. e. when knitting, the annular shuttle 29 lies on an annular holder 30which is mounted to swing up and down at 32 on the bottom of the casing6 by means of an arm 31, and is held both in its vertical and in itslowered position by` a bent, laterally resilient arm 33.

Immediately behind the gripper there is fast on the shaft 15 a cam disc34 which serves for lifting the material transporter 35 (Figs 1, 3, 6and 7). In Figure 1 this transporter is not shown because the sewingmachine is used for knitting in the position in which it is shown. Thistransporter 35 is at the free end of a lever 36 pivoted to a lever 37whose shaft 38 is driven by a device described hereinafter. When not inuse the transporter 35 liesswung away to one side as shown in Figure 3and in broken lines in Figure 6.

The shaft 38 lies parallel to the shaft- 15 and carries fast on its rearend, away from the lever 37, a lever 39 to which a swinging member 40(Fig. 22) is pivoted. This member 40 is mounted on a pivot 41 of a slideblock 42 slidable in a link 44 able to rock about a pivot 43 carried inthe pedestal of the upper arm 2. The upper end of this swinging member40 is forked at 45'and embraces a cam disc 46 fast on the main sha-ftSinker needles 71 (Fig. 3)v are situated be- 3. When the cam 46vrotates, the member 40 is rocked to and fro about the plvot 47 y on thelever 39 and theA block 42 is thereby reciprocated in the link 44. Asthe latter is placed slantwise the swinging member 40'1s `simultaneouslymoved up and down, this movement being more or less according theposition of the link 44. The shaft 38 1s thereby oscillated, by whichthelevers 37 and 36 are reciprocated with the transporter 35 which duringone of its long1tud1 nal movements is lifted by the cam 34 into theoperative position indicated'm broken linesY in,Fig11re 6. I v

A hollow shaft 48 is slidable lengthwlse on the shaft 15, and isprovided at 1ts front end with a control disc 49, to whose front face acam 51 is attached by means of a.

osition of the etachably couscrew 50. In the front end hollow shaft thiscam 51 is pled with the shaft 15 by a pin 151 that is arranged on theshaft 15 and enters into `a recess 511 of the disc open at the front.The disc 49 has at its rear side a cam groove 52, in which runs ananti-friction roller, 53 (Fig. 4) mounted on an arm 54 of alyoke 55.'lhis yoke of U-sha-pe is mounted to swing laterally about a ivot 56fast on an e e 57 of the slide 8. t the upper end o the yoke 55 are twobolts or studs 58, one 1n each limb, which bolts together carry at theirfront ends a fiat bow 59 having in the middle two s aced, rearwardlydirected, oppositely bent ooks 6() serving as loop 'o ener (Figs. 19, 18and .29). Outslde the hoo s 60 two fingers 6l extend rearwardly andprevent the loop from being opened too wide by the gripper.

Two rearwardly extending, upwardly bent levers 63 Fig-3) areJournaled'coaxially in the si e walls of the slide 8, each on a pivot62. A cross-bar 631 connecting these levers together carries in themiddle an antifriction roller on a rearwardly directed arm 64 extendingslantingly u wards; this roller 65 is lpressed against t e periphery ofthe cam 51 by the action of a spring 66 pressing upwards one of thelevers 63 which are thus controlled by the cam. The levers 63 carry attheir upper lends a cross-bar 67 (Figs. 4 and 13) connecting themtogether and having in the middle two upwardly and forwardly 68 whichtogether constltute a loop holder. The distance between these points ofthe loop holder is so great that the needle 28 can readily pass betweenthem. The cross-bar 67 is provided between these points with a recess 69permitting the needle to pass through it. The points serve f orwithdrawing atloop 70 from the loon or sinker needle 71 above them andfor holding open the extending points 13 on the bottom of the casing.

thinner and less high than the stem 71",

In order to facilitate the loop-holder points 68 passing through a loopon the sinker ne'edle, the latter is provided at the top of` its pointwith two lateral lugs or flanges 71"', so that the needle point is ofT-section. at

that part, as shown 1n Figure 26. A thread.

embracing the needle at this place therefore leaves, as indicated inbroken lines in Figure 26below the flanges sufficient space for theentry of the points 68 into the loop. The sinker needle 7l which issituated just under the knittin needle 28 is drawn back, when the latterdescends, by the device described hereinafter so that it disap earscompletely with its point under the p atc 72, andthe latter removes fromits olnt the loop 70 onl the needle in question (Fig. 15).

The shaft of each vsinker needle is provided at its rear free end on itslower side with a recess 75. Into the recess of the sinker needlessituated beside the needle 28 there extends, from below, a cross-bar 76(Fig. 1) fastened to the side walls of the slide 8, by which bar all thesinker needles are lheld against forward and backward of the sinkerneedle situatedlielow the needle 28 a nose 77 of a rod 78 which isguided to move lengthwise under the sinker needle in question 1n acorresponding recess 79 of the cross bar'- 76 and in the rear end wall 8of the slide 8. The rod 78 is 4engaged by means of a downwardlyextendingroller 8O with a cam groove 81 of a control drum 82 at the rearend of the hollow shaft 48, by which drum lthe rod 78 and the sinkerneedle 71 coupled with it is retracted and )lished forward with eachswing ofthe sha t 48.

In order that at each swing of this shaft 48a different sinker needlemay be actuated, the slide 74 which is guided in suitable recesses intheside walls of theslide 8, is shifted with all thev sinker needles a stepequal in length to the thickness of the latter. For this purpose theslide 74 is provided on its underside with a toothed rack 83' with whicha pinion 84 meshes (Figs. 1 and 3). This imon is fast on a shaft 85journaled paral el to the shaft 15 in bearings 86 on the one side wallof the slide 8 and in the arm The shaft 85 carries beside the `pinion 84a ratchet Wheel 87, in which engages-a detent 88 which is bevelled onboth sides and is carried by a spring 89 secured on the slide 8, wherebythe l10o l movement. There engages in the recess 75 shaft 85 and with itthe slide 74 is held in a given position. The two wheels 84 and 88extend into a recess 90 of the ad'acent side wall of the slide 8, sothat when t e latter is 5 shifted the shaft 85 moves with it.

At its rear end the shaft 85 carries close together two ratchet wheels91 and 92 (Figs.

8 and 9) having oppositely directed teeth. In the working position ofthe slide 8 these 10 wheels 91, 92 are situated within reach of two'pawls 95 and 96 rotatable about two pivots 93 and 94 on the gear wheel17, each of which pawls is held under the influence of a spring 97bearing against a pin 98 and lies in the general plane of its allottedratchet wheel. Accordlng to the position of the link 23 and consequentlyaccording to the lworking direction of the link 19 trhe pawl 95temporaril engages with the ratchet N wheel 91 ory t e awl 96 with theratchet Wheel 92. The siaft 85 is rotated by the pawl 91 in onedirection and by the pawl'92 in the opposite' direction and consequentlythe slide 4 is fed one step in the correspon ing direction in each case.In order automatically to change the direction of feed the followingdevice 1s rovided.

Two arms 99 1g. 5) extend from the slide 74 to the rearbeyond the sinkerneedles 71. At the rear ends these arms 99 carry a rod 100 that isparallel with the slide 74 and has line toothing on its underside. Onthe rod 100 are two stops 101 and 102 which are pressed upwards by leafsprings 103 (Fig.

5) housed in them so that teeth 104 formed on their lower parts meshwith the toothing of the rod 100 and are thereby held at thefdesiredposition, and extend upwards through a slot 1 in the base plate '1. Whenthe stops 101 and 102 are depressed against the action of their springs103 they can be shifted along the art of the rod 100 carrying them andbe a justed as desired. A two-armed lever 105 free to rotate about thehollow shaft 48, the two ends of which lever are forked, extends frombelow the stops 101 and 102 into their reach. The lower end of thislever 105-embraces va pin 106 which extends rearwardly from a lever 107of a shaft 50 108, so that the lever 105 can slide on the pin to therear without leaving it. The shaft 108 is )journaled on the one hand inthe rear wall 8 of the slide 8 and on the otherhand in the rear wall 84ofthe casing 6. On the rear end of the shaft 108 is' fast an upwardlyextending arm 109 and behind this are pivoted the two paWls 26 and 26aforesaid. These awls are provided each with an executive ug orextension 112 and 113, to each of which is attached from below a tensionspring 114, so that the pawls always bear against stops 115 extendingfrom the wall 24, b which their upward movement 1s limited. ln thisposition the free ends of the pawls 26 and 26 are within reach of the aslot 110 in the lever, is rocked by the shaft 108 out of its endposition indicated in broken lines in Fig. 10 into the end position`shown in full lines, Which occurs at the moment when the block 22 is inits upper end position, the rod 117 is brought by its link 119' into thereach of a rojection 120 of the block y22 that lies out o the generalplane of the lever 109. This block 22 has on its opposite side a similarhorn-like projection 120 for the rod 118. When the block 22 descends andits horn 120 strikes the rod 117, the pawl 26 is moved by the latterdown out of the link 23. Shortly afterwards the block 22 hits againstthe upper end of the arm 109 With a shoulder 120 arranged on the horn120. A torque is now exerted to thev left on the block by the arm 109and asthe pivot pin 20 of the block has arrived .in alinement with thepivot 25 of the link 23, and the latter is thus relieved from any forceacting on it, the link 23 swings from the position shown in Fig. 10 intothat according to Fig. 11. In this position the link is arrested by thepawl 26.' The changed posi` tion of the link 23 then occasions therocking of the link 19 of the wheel 17 to the opposite side so that thepawl 96 then begins to coact with the ratchet wheel 92 which turns theshaft 85 intermittently in the o `posite sense and thereby shifts theslide 4 with the sinker needles to the opposite side. In order that whenthe slide 8 shifts the Vhollow shaft 48 may also be moved the latter isprovided in a head 121 with an-annular groove 122, into which thereengages from below a fork 123 fast on an arm 8 of the slide 8 (Figs. 1and 5).

A downwardly curved frame 124 serves for holding the work, which frameis surrounded by an elastic tie, for example an endless coil spring, 125which lies in a groove 126 in the frame and tightly stretches on thelatter a piece of work drawn down over it. The frame 124 is so suspendedby means 0f two arms 127 that it can swing forwards and backwards on twocurved standards 128 mounted detachably in the slide 74. These standardsextend upwards through an aperture 129 in the plate 1 and are removedfrom the slide 74 when the machine is to be used for sewing. After theremoval of the standards or posts 128 from the slide 74 the rear part ofthe a erture 129 can be closed by a flap 130 whic is hinged at 131 tothe pnate 1 and is folded back to the rear durin itting, as shown inFig. 1. The front en CTI Lampes of the aperture 129, which affordsaccess t0- the gripper and shuttle, can be closed las -usual by asliding shutter 132.

The manipulation Iand operation of the described 4machine for knittingmay be briefly described as follows The slide 8 is irstset in its frontend position. After turning back the flap the standards 128 are placedinto the slide 74 and the frame 124 provided with the work is hung onthe standards. The shuttle holder 30 is set in its inclined Cposition,so that the shuttle 29 is removel from the gripper r27 "and lies in 'theholder' 30.

The'transporter 35 is swung outwards as shown Yin Fig. 3. By rotatingthe main shaft 3 the thread feeder 5 and the needle rod 4 are actuatedin the usual manner. The connecting rod 21 turns the toothed .wheel 17to and fro in the manner described Vsame time, arrives vat the height ofthe sinker needle. As the sinker needle recedes the loop holder 67, 68moves forward. The loop holder does not assist in formlng the first rowof loops. The needle 28 descends into the gripper 27 (Figs. 16 and 17)which makes the threadin the usual manner (as when sewin in the form lofa loop which, during its formation, is held open by the rearwardlyswungl hooked bow 59, 60. When the sewing needle ascends and the loop isdrawn upwards the latter is hung on the simultaneously advancing sinkerneedle. At the moment when the needle 28 and the pivot 30 have reachedtheir upper end positions the shaft 85 and with it the slide 74 is fedone step b one of the pawls 95 and 96, whereupon t e cycle of operationsfor forming another loop can begin afresh.

Assuming thatthe first row of loops or any subse nent one has been madethe operation of orming a stitch is as follows When the needle 28descends and the sinker needle recedes the loop of' thread han ing onthe latter is swept olf by the cover p ate 72 and as soon as it 1ssituated on the flanges 71 is seized by the forwardly moving loop holder68 (Figs. 14 and 15) and is so brought into the pathof the needle 28Vthat this, after piercing the work, enters through.

the loop into the gripper 26 (Figs. 16 and 17). In the lowest positionof the needle' 28 the loop holder-'68 recedes and releases below thelatter the the 4old stitch. The tgripper 27 then seizes read of theneedle 28 and forms the loo for the new stitch (Figs. 18 and 19). Be orethis loop is released by the gripper the sinker needle 71 passes throughit (Figs. 20 and 21). After the release of the loop it is pulled tightby they thread feeder until it lies on the sinker needle. In the upperend position of the needle 28 the shaft 85 is fed one step with theslide 74 and the entire row of sinker needles, whereupon a new stitch`i's formed in the manner described above.

The stops 101 and 102 are set on the rod 100 according to the breadth ofthe row of stitches to be formed. As soon as one of these stops hits thelever 105 (see stop 102 in Fig. 5) the lever 109 is reversed b the lever105, pivot 106, lever 107 and sha t 108. The link 23 is then rocked"from one end position into the other in the above described manner atthe next descent of the block 22 by the rod 117 or 118, whereupon theslide 74 withthe sinker-needles is fed in the op osite direction. Themovement of the wor frame from one row of stitches to the next before anew row begins is brought about by the action of a spring or weight notillustrated. The last row of stitches is simply knitted or, if desired,-sewn to the work. n

The use of the machine for sewing will be readily understood. The posts128 with the frame 124 are removed from the slide 74. The slide 8 isshifted into its rear end position indicated in broken lines in Fig. 1together with the members used for knitting connected with it. Theshafts 48 and 85 are thereby moved endwise. The shaft 48 is disconnectedfrom the pin 15 'so that, during sewing, the gripper shaft 15 which isnot movable endwise, can alone rotate.y When the shaft 85 movesbackwards theratchet. wheels 91 and 92 move out of the reach of thepawls 95 and 96.. Then the work transporter 35, 36 is swung inwardsinto, its working position. The aperture 129 is closed by the cover 130and shutter 132 after the spool holder 30, 31 with the spool 29 has beenswung up. `After the other operations usual for sewing have beenperformed, the machine can be used for sewing.
